THERMOMETER ATTACHMEN T FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 282,770, dated August.7, 1883,

Application filed April 7, 1883. (No model.)

To all whom it may concern:

Be it known that I, SEYMOUR RAYMOND, a citizen of the United States, anda resident of Middletown, Dauphin county, Pennsylvania,

have invented an Improvement in Thermometer Attachments for Stoves,Ranges, &c., of which the following is a specification.

The object of my invention is to so combine a thermometer with the dooror casing of a stove, oven, or range that the thermometer will be belowthe outer surface of the door or casing and protected from injury, whilethe mercury-bulb will be exposed to the direct heat within the stove,oven, or range, as more fully described hereinafter.

In the accompanying drawings, Figure 1 is a front view of a cookingstove or range door with my improvement applied thereto; Fig. 2, avertical section on the line 1 2, Fig. 1; and Fig. 3, a section on theline 3 4.

I11 the face of the door or casing is formed a slot, A, of about thewidth of the thermometer B to be applied thereto, but not quite so long.This thermometer is constructed of the usual sheet-metal plate, I),to'which is secured the mercury-tube b and bulb b the latter projectingbelow the bottom of the plate I), as shown in Fig. 2. The plate I; isnot marked with the usual graduations, but the thermometer is speciallyprepared for the purpose and graduated to indicate from 150 to over 600Fahrenheit, as shown in Fig. 1.

The thermometer thus constructed is secured in the bottom of anopen-faced box, D, corresponding with the slot A in, the door, butsomewhat longer, and this box is secured in position on the inner sideof the door or casing,with the graduated face of the thermometeropposite the slot. I prefer to secure the box by means of bolts and nuts0, passing 0 through flanges d on the box.

The bulb of the thermometer is below the bottom of the slot A, Fig. 2,and a cross-piece,

d, may be placed across the box on a level with'the bottom of the saidslot to protect the 5 bulb from the atmospheric air, and at the sametime prevent the escape of heat from the oven at that point.

The bottom of the box D is slotted preferably throughout the length ofthe tube,'as well as opposite the bulb, and as the latter projects belowthe plate b it is exposed to the direct action of the heat in theinterior of the oven. At the same time, the whole thermometer beingsecured in the bottom of the box below the face of the door or casing,it is well protected from injury. a

Although I have shown the thermometer as applied to the door near thehandle, it may be applied to the door or casing at any other convenientpoint.

I do not desire to claim, broadly, .the combi nation of a thermometerwith a stove door or casing; but

I claim as my invention- The combination of the door or casing of astove, range, or oven having a slot, A, with a box, D, secured to theinner side of said door or casing in line with said slot, and carrying athermometer, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

SEYMOUR RAYMOND.
